RSI offers a chance to define the market sentiment and spot the points at which the market is overbought and oversold.

It is also used to detect times when the price is about to reverse, and a new trend rises.

Features and Advantages of The RSI Indicator

As any other oscillator, the RSI indicator is not plotted on the price chart, but in a separate window below. This technical instrument consists of a single line and two levels set by default.

Vertical axis range of the indicator is set to 1 to 100 showing extremality of current price against its previous values.

 

RSI values calculation

RSI = 100 – (100 / (1 + U/D))
Where:
U – average number of positive price changes
D – average number of negative price changes

What the formula means, is that if the price grows against previous values, so does indicator reading; otherwise, oscillator’s value goes down.

The RSI line may reach 0 or 100 only during strong, continuous downward or upward trend, respectively.

RSI indicator on the chart

Usually standard overbought and oversold levels are 70 and 30. If the indicator’s line goes above the 70 level, it signals that market is overbought and the trend may reverse downwards.

If the indicator’s line goes below the level 30, it signifies that market is oversold and the trend may reverse upwards.

The reference level is 50, and it is the median value. If the indicator chart is ranging between the levels 30 and 70, the market is flat or that the current trend is smooth, steady and there is less of a likelihood for reversal in short-term

Sometimes, overbought and oversold levels are set at 80 and 20 instead of 70 and 30. This setting is used during increased market volatility.

Setting and Adjusting RSI Indicator

There are two ways to set up this indicator. The easiest way is to click the tab ‘List of Indicators’ located on the upper panel of the terminal and select ‘Oscillators’ – ‘Relative Strength Index’.

The indicator installation on the chart

Another option is to choose ‘Insert’ – ‘Indicators’ – ‘Oscillators’ – ‘Relative Strength Index’.

The RSI Setting

Instrument configuration window will open before the indicator is set in the chart. This window allows you to configure the indicators parameters.

The main parameter is the period; It defines the number of price values taken into consideration at plotting the main indicator’s line. The shorter the period, the steeper indicator’s chart movements will be.

This parameter is set to 14 by default, and this setting is considered optimal in most cases. You can also adjust the style settings, like line colour and weight.

By using another tab of configuration window, you can change parameters of the levels from 30 and 70 to 20 and 80. You can also add new levels should your trading strategy require so.

Opening Positions on RSI Signals

The main signal the RSI oscillator generates allows defining overbought and oversold price ranges.

Although it is frequently used as a filter in systems where the main indicator is a trend one, it might be possible to try trading using RSI signals only.

When indicator’s line goes above the level 70 or below the level 30, it signals that market is overbought/oversold, and it is necessary to wait for the next signal confirming a trend reversal.

These are the rules for opening positions based on the RSI signals:

  1. If the indicator’s line crosses the level 70 from above, a short position (Sell) is opened.
  2. If the indicator’s line crosses the level 30 from below, a long position (Buy) is opened.
RSI trading

There are several conditions for closing a trade:

  1. Place a Stop Loss to local extremum and Take Profit to the value that is by 2-3 times greater.
  2. Exit on opposite indicator’s signal.
  3. Place a Stop Loss and Take Profit to the nearest key levels or Fibonacci (here Take Profit level should be not less than Stop Loss otherwise it is better to hold back and avoid opening a trade).

However, trading using RSI signals only is not the best approach as it has been designed to be used as a filter and not the main instrument.

A trading strategy will be more efficient when using a trend indicator or at least paying attention to the Price Action signals.

Combined Strategy using Stochastic + RSI

In order to boost trading efficiency, it’s best to use the Stochastic Oscillator. The absence of trend indicators in this trading strategy is compensated by simultaneous analysis of two timeframes.

This way the oscillators will filter each other’s signals and trades will be opened only when both indicators give the same signals on different time frames.

This strategy suggests using time frames of Н4 and М15. In Н4, the RSI will have the default settings.

The only difference will be that instead of levels 30 and 70 we will set it at 50. In М15, Stochastic will have default settings.

Short position (Sell) will be opened in the following case:

  1. In Н4, the RSI line is crossing the level 50 from below.
  2. In М15, Stochastic lines exit overbought zone and heads down.
Trading using Stochastic + RSI signals

Long positions (Buy) will be opened in the opposite case.

Stop Loss and Take Profit are fixed and set at distances 20 and 50 points from the opening price respectively.

Such ratio enables to obtain a positive statistical expectation from trading in the long run.

It is recommended to check the economic calendar before opening positions in this trading system since the release of important news can significantly influence price movement, and technical analysis won’t be relevant at this very moment.

Advanced Strategy RSI + Stochastic + МА

Finally, let’s consider strategy with three classic indicators filtering each other as a single set and giving powerful forex signals for entering the market.

This strategy fits best for trading on Н1, Н4 and D1.

First, it is necessary to set up the following indicators in the chart:

  1. A moving average with the period of 10.
  2. An RSI with standard settings (levels 70 and 30).
  3. A Stochastic oscillator with standard settings (levels 80 and 20).

According to this strategy, a long position is opened when the following signals are generated:

  1. Price is crossing МА from below.
  2. RSI and Stochastic exit oversold zone.

All three signals should be received during three candles, otherwise, they will lose their value.

Advanced Strategy RSI + Stochastic + МА

Short positions (Sell) should be opened in the opposite case.

Exiting an open trade should be done when RSI enters the opposite zone. Sometimes, an opposite position can be opened simultaneously with closing previous position, granting other signals to follow the abovementioned pattern.

Conclusion

The RSI is one of the main indicators of technical analysis, and almost all the forex trading experts think that it is still very useful and valuable as a source of trading signals.

The success of trading with an RSI depends on using additional indicators in conjunction with it.

Combined with the right indicators, RSI forms an efficient system, which can be fine-tuned by amending the parameters of instruments used.

Main RSI Trading Strategies FAQ

  • How do you find Overbought and Oversold Levels with the RSI?

    The Relative Strength Index, or RSI, is used to locate overbought and oversold conditions in financial markets. As an oscillator type indicator it does this by moving up and down within a range of 0 to 100, with 0 representing the most oversold conditions, and 100 representing the most overbought conditions. Typically any reading above 70 is considered overbought and ripe for a reversal, while readings below 30 are considered oversold and also ripe for a reversal. Some traders use the 80 and 20 levels as their signal points.

     
  • How to use RSI in a Trending Market?

    Because the RSI is typically used to detect overbought and oversold markets some traders feel it can’t be used in a trending market, but nothing could be further from the truth. One RSI trading strategy used in trending markets would be to wait for the indicator to signal an overbought condition during an uptrend. The trader then waits for RSI to drop below 50, which signals a long entry. If the trend remains in place price will typically recover off this level and move to new highs.

     
  • How do we Discover New Price Trends using RSI Divergence?

    Using divergences between the RSI and prices on the chart is considered as an aggressive use of RSI, but it also allows trends to be discovered early, thus leading to greater profits. For example, in a downtrend we might see lower bottoms for prices, but higher bottoms on the RSI. This indicates the strength and momentum of the downtrend is decreasing, which makes an upturn in price more likely. The same is true in an uptrend, although there we would see lower highs in the RSI, while higher highs are still being reached on the price chart.
